I enjoyed this article in St. Anthony's Messenger: Spiritually Healthy Children by Alicia Von Stamwitz. It offers a great deal of practical advice and emphasizes that what our children see us doing is far more important than what we are saying. What type of example are you giving your children?
As Von Stamwitz states, "If you want your child to breathe in deeply the spirit of God, you too must breathe deeply. you must explore the values and cultivate the practices that help you live out your own dignity, goodness and creativity."
